solvefor x,x^2+y^2-14x-2y+50=x^2+y^2-6x-10y+34

解答

求解

x, x^{2} + y^{2} - 14 x - 2 y + 50 = x^{2} + y^{2} - 6 x - 10 y + 34

解答

x = y + 2

求解步骤

x^{2} + y^{2} - 14 x - 2 y + 50 = x^{2} + y^{2} - 6 x - 10 y + 34

两边减去

x^{2} + y^{2}

x^{2} + y^{2} - 14 x - 2 y + 50 - (x^{2} + y^{2}) = x^{2} + y^{2} - 6 x - 10 y + 34 - (x^{2} + y^{2})

化简

- 14 x - 2 y + 50 = - 6 x - 10 y + 34

将

2 y

到右边

- 14 x + 50 = - 8 y - 6 x + 34

将

50

到右边

- 14 x = - 6 x - 8 y - 16

将

6 x

para o lado esquerdo

- 8 x = - 8 y - 16

两边除以

- 8

x = y + 2

a^2+r=(a+r)/(2a+1)

a^{2} + r = \frac{a + r}{2 a + 1}

(3^2x+3)/(9^3)=9^{14}

\frac{3 ^{2} x + 3}{9 ^{3}} = 9^{14}

solvefor x, 111/11 x-301/13 y=0

so l v e f or x, \frac{111}{11} x - \frac{301}{13} y = 0

solvefor x,0.2x+0.8y=9.1

so l v e f or x, 0.2 x + 0.8 y = 9.1

solvefor x,x+13=12y

so l v e f or x, x + 13 = 12 y
